Sustainability in Membrane Technology: Membrane Recycling and Fabrication Using Recycled Waste Membrane technology plays a crucial role in addressing water scarcity, but end-of-life membrane modules pose environmental challenges due to incineration and landfill disposal. Recycling membranes and using recycled waste materials for membrane fabrication can enhance environmental sustainability. This review discusses membrane recycling and fabrication using recycled waste, emphasizing the integration of sustainability concepts into membrane technology. Membrane recycling involves reusing membranes for similar or upgraded/downgraded operations, while polymer recycling aims to recover polymer for re-preparation. Techniques such as regeneration, upcycling, downcycling, and re-preparation are explored. Regeneration involves using eco-friendly solvents to restore membrane performance, while upcycling transforms end-of-life membranes into new membranes with improved properties. Downcycling converts membranes into lower-performance membranes, and re-preparation involves dissolving membranes to fabricate new ones. Recycling polymeric membranes can reduce resource and water scarcity while minimizing waste. The use of recycled waste materials such as polystyrene, polyethylene terephthalate, polyvinyl chloride, tire rubber, keratin, and cellulose can enhance environmental sustainability. This study highlights the potential of recycled materials in membrane fabrication, demonstrating their effectiveness in reducing environmental impact and promoting sustainable practices. The review also discusses the fabrication of membranes using recycled waste, including polystyrene, polyethylene terephthalate, polyvinyl chloride, and tire rubber. These materials offer promising alternatives for membrane production, reducing the environmental footprint and promoting circular economy principles. The study emphasizes the importance of sustainable practices in membrane technology to address environmental challenges and promote resource efficiency.Sustainability in Membrane Technology: Membrane Recycling and Fabrication Using Recycled Waste Membrane technology plays a crucial role in addressing water scarcity, but end-of-life membrane modules pose environmental challenges due to incineration and landfill disposal.
